OIL-BURNER.

Specification of Letters Patent.

Patented Sept. 25, 1917.

Application filed December 29, 1916. Serial No. 139,602.

To all whom it may concern lie it known that I, ELMER G. LANTZ, a citizen of the United States, residing at Tillamook, in the county of Tillamook and State of Oregon, have invented new and useful Improvements in Oil-Burners, of which the following is a specification.

The invention relates to burners, and more particularly to the class of oil burners.

The primary object of the invention is the provision of a burner of this character wherein the oil is vaporized prior to the consumption thereof by the flame, and the parts of the burner are materially simplified so as to eliminate complication and difliculty in the cleaning thereof.

Another object of the invention is the provision of a burner of this character wherein there is arranged an adjustable .flame spreader or combustion pan which slides back and forth on the generating pipe of the burner, thereby controlling the fire or flame topermit keeping the generating pipe hot with a small fire and thus eflecting a saving of fuel consumption.

A further object of the invention is the provision of a burner of this character wherein the fuel nozzle is of a novel construction so that it can be readily cleaned at the point of the aperture to avoid the choking or clogging thereof.

A still further object of'the invention is the provision of a burner of this character which is extremely simple in construction, thoroughly reliable and efficient in operation and inexpensive of manufacture and installation.

Other objects will be in part obvious and in part hereinafted pointed out.

The invention accordingly consists in the features of construction, combination of elements and arrangement of parts which will be exemplified in the construction hereinafter set forth, and the scope of the application of which will be indicated in the claims In the accompanying drawings:

Figure 1 is a side elevation of a burner constructed in accordance with the invention;

Fig. 2 is an end elevation thereof;

Fig. 3 is a top plan View.

Fig. 4 is a vertical longitudinal sectional view through the body;

Fig. 5 is a perspective view of the sliding flame spreader or combustion pan; and

66 of Fig. 1.

Similar reference characters indicate corresponding parts throughout the several views of the drawings.

Referring to the drawings in detail, the burner comprises a generating pipe 10 which may be of any desired length and has connected thereto through the medium of a reducing nipple 11, at one end thereof, an oil supply pipe 12, while at the opposite end of the generating pipe is mounted a gooseneck shaped nozzle 13, having the straight portion 14 parallel with the generating pipe 10, and this straight portion 14 at its inner perforated end 15, is formed with a central aperture 16 through which is emitted the fuel for consumption, while adjustably threaded in the outer open end of the straight portion 14 is a bushing 17, through which'works an adjusting stem 18 formed at its inner end with a cleaning head 19 provided with a pointed tip 20 which is adapted to enter the aperture 16 for removing any particles of dirt-therefrom on the inward movement of the stem 18, the stem 18 being formed with external threads 21 to engage in companion threads 22 formed internally of the bushing 17, so that the head 19 can be locked with the bushing to hold the head retracted with respect to the perforated end 15 of the straight portion 14 of the nozzle. The outer end of the stem 18 carries a knurled disk 23 which permits the turning of the stem to unlock the same from the bushing 17 for permitting the inward movement of the same to force the head 19 in the direction of the perforated end 15 of the straight portion 14 of the nozzle, whereby the tip 20 will be inserted in the aperture 16 for the cleaning thereof. Surrounding the stem 18 without the nozzle is a coiled expansion spring 24 which serves to automatlcally move the cleanlng head in an outward direction toward the bushing 17 so as to hold the said head and its tip away from the apertured end of the straight portion of the nozzle.

I Movably supported upon the generating pipe 10 is a flame spreader or combustion pan which comprises a trough 25 formed with a reduced forward nose end 26 and also provided with upstanding cars 27 which are spaced from each other and are formed with openings 28 to accommodate the generating pipe 10, and in this manner the said a mum consumption of. fuel.

flame spreader or combustion pan is hung suspended from the said generating pipe,

By reason of the mounting of the flame spreader or combustion pan upon the generating pipe 10 the flame from the fuel dis charged, through the nozzle 13 is permitted to'play upon any portion of the generating pipe and when the spreader orpan is shifted close to the nozzle 13 it confines the flame to a small space in the front of the, stove, thereby keeping the generating, pipe hot witha small fire and with resultant mini- However, by sliding the spreader orl pan awayfrom the .nozzle 13 the extent of theflanie is increased upon thegenerating pipe, thereby increas- 111g the heatwithin the, stove to any point ,desired. Arranged within the; oil supply ,pipe 12 is a cut-off valve. 29 which controls the supply of fuel or oil to the burner nozzle, as will beclearly apparent.

From the foregoingdescription, taken in connection with the, accompanyingdrawings the; construction and operation of the invention will bereadily apparent, and a ,more, extended explanation, therefore, has

been omitted;

Having thus ,described my invention, I claim:

1. A burner of the class describedcomprising a generating tube, a burner nozzle connected ,therewithand having an aperture, a tubularr;,bushing threaded into the burner nozzle opposite said, aperture, a valve rod slidable through said bushing, a head on the valve rod, the ,bushing being internally threaded and the head being externally threaded for engagement, with the-interior threads :of the bushing whereby the head is qopies o t thts -paten t may beobtained to aperture, a a-tubular bushing threaded into the burner opposite the discharge aperture, a valve rod slidable-through the bushing, a

head. .on the valve rod having a cleaning tip .adaptedto be inserted in said aperture, spring means for retracting the head, the .bushingbeing internally threaded and the head being exteriorly threaded andnieans for rotating .thevalve ,rod tolockingly en- :gagethe head with or to disengage the headfromthe internal threads of thebushting. 1

3. A burner of the class described, comprising a horizontal generating tube, a burner nozzle connected therewith havmg a 'discharge, aperture with. its axis substantiallyparallelwith thegenerating' tube, a

trough like combustionpan, a pair of ears formed on the combustion pan and slidably engaging the generating tube to support the combustionnpan, the ear'adj acent the nozzle being spaced-cfrom'ithebottom of the pan" thus allowing passage of-flame to' theirear .ofthe pan and the second ear serving. to close-such end'of thevc'ombustion pan. i ln-testimo'ny whereof I afiixmy signature in presence of two witnesses.
